The unfreezing took place after the exchange suspended the deposit and withdrawal business last August because of the widening price differences between home and abroad on these cryptocurrencies.
Following the freeze, the price differentials for these cryptocurrencies have widened up to more than five times.
The unfreeze would encourage investors to transfer their holdings to Bithumb for price arbitrage.
The rush of price arbiters would increase the exchange’s trading volume, a Seoul broker said.
Unlike stocks and bonds, cryptocurrencies have more than two prices at different exchanges.
Whether in New York or Seoul, a Samsung Electronics stock price is the same. However, a cryptocurrency could be $1 in New York and $2 in Singapore.
